A set of settlements in a certain area arranged according to size is characterized by a distribution suited to generalization and mathematical presentation. This paper discusses the rank and size rule presented in the form of an equation: Pj=P₁ • j-a=const, where: Pj - number of population in settlement j, P₁ - number of population in the largest settlement in the studied class, j - position of settlement after arrangement according to decreasing size (rank), a - contrast exponent of settlement network and tgπ
